E10 finally coming in...

I had an issues earlier this month from what I now presume was my first fill of E10 back in July. Classic hot start issues, would just randomly die when hot and refuse to start until it cooled down a bit, car down on power also.

Drained the tank and the fuel was very cloudy and not the crystal clear you'd normally expect. The tank had only been cleaned last winter so I'm confident there weren't any issues with it.

Not willing to bin 40l of petrol, I refilled with the appropriate amount of E10 additive and the car has run perfectly since.

Ye, I think I'll be leaving little enough in it over winter, might just drain the system and throw it in my daily. At the moment I have a bottle of Wynn's E10 protector I'm using, but I'll be shopping around online over winter for some as prices seem to vary wildly for them.

A question for any Wynn's users. With the last two bottles I got I ran into a problem. The cap is one of those kid safe ones where you have to push and turn, in both bottles once I got down to the last 3rd of it, the top of the bottle collapsed under the pressure of pushing down on the cap and it took ages to open the bottle again.

Anybody else experience this?

Thanks, yeah, I think I was holding it with the main part of the bottle, I'll try as you suggest. For now I just very lightly screwed the cap on. Crazy we have to do this, when I was a kid my mother just said don't drink the bleach etc, and I didn't . Progress, eh :)

I've done about 1,500 miles with E10 without any issues, using Wynn's plus just filling up with 25L at a time so it's not sitting too long.

I'm due an oil change in the next few months so I'll inspect the fuel lines while under the car.

So, you have been sitting with a tank of E10 since the summer? I believe one of the issues it that is could absorb moisture and rot the tank from the inside.

Good to hear it's not just me! Yes I just very lightly screw the cap on now, before it "clicks". And yes, it could be better for putting in the tank. Should be like the Dipetane bottle and have a long neck.

I suspect that hose is not rated for the high pressure side of the fuel injection system hence the splitting and bulging. Those clamps are certainly not recommended unless there are barbs on the solid line they attach to. Also J30R7 is standard fuel and oil line for low pressure, you need J30R9 for fuel injection systems on the high pressure side. Replace with hardline or correct fitting rubber lines. The rubber lines will require at least a flare on the hard lines.

Halfords actually sell R9 rated fuel lines, they call it fuel injection hose, just need to keep an eye out. I know the Kjetronic well, it was on a few 80s and early 90s cars. It is sensitive to pressure though but a reliable system. Easier to get parts for than the earlier D jetronic system.

Regarding the clamps, as said earlier they are suitable if there is a barb or slight bubble on the solid fuel line the flexible fuel line attaches to. I would not be overly confident if they are purely relying on a friction fit to straight line. Most oem flexi lines would have a crimped fitting that is mechanically attached to a solid line.

I ended up getting some R6 from Halfords. I went to and rang a few places and nobody could tell me what spec they sold. so I went to Halfords as they have the spec. That was all they had in 8mm. It's rated at 20 bar working pressure. I only had today to get it done so had no choice, I'll keep an eye on it.

WRT the clamps, the hard lines have no barb or anything like that, so I just put 2 x jubilee clip at each end and ran it for 10 min, all ok

Thanks. I'll have to get some R9 and replace all the lines at some stage, but hopefully this will do for now. And, I always put the additive in.

Thanks @w124man I'll have to source some better lines and replace them later.
